But there will always be deficiencies in testing, and regardless, the point is that Anthropic is intentionally introducing behavior into their models which increases the chance of a deficiency being introduced specifically as it pertains to defense.

The DoD has a right to avoid such models, and to demand that their subcontractors do as well.

It’s like saying “well I’d hope Boeing would test the airplane before flying it” in response to learning that Boeing’s engineering team intentionally weakened the wing spar because they think planes shouldn’t fly too fast. Yeah, testing might catch the specific failure mode. But the fact that your vendor is deliberately working against your requirements is a supply chain problem regardless of how good your test coverage is.
